AMO and Powerpoint - Creating Multiple Charts from Same Dataset

Does anybody have more detailed documentation on using the AMO with Powerpoint than the basic AMO users guide? I want to use the AMO to create 20-30 charts in a Powerpoint Presentation, and want to know the most efficient way to refresh the data behind the charts when the dataset updates, without having to press refresh on each chart. I'm using AMO 4.3. Thanks...
